Both for its historical and linguistic merits, the document which is presented in this volume is one of the most important in aboriginal American Literature. Written by a native who had grown to adult years before the whites penetrated to his ancestral home, himself a member of the ruling family of one of the most civilized nations of the continent and intimately acquainted with its traditions, his work displays the language in its pure original form, and also preserves the tribalhistory and a part of the mythology, as they were current before they were in the least affected by European influences.
